I'm kind of in the same boat as the OP. I have been thinking about ditching sense for a bit, at least until we get some sbc kernels. So I starte dlooking for an AOSP rom. I've tried CM7 before, but not a fan of all the fixes it requires. I'm always afraid I didn't do something and then something won't work when I need it to.
I tried Evo deck, and I love the rom, but I think it has given me a wake lock problem that I can't seem to fix. I've tried flashing the radios that are known to fix the wake lock issue, and also a new dialer apk, which is supposed to fix this issue. But still my cell standby time matches my uptime.
I tried vaelpak 4 preview 0.2.2. I can't remember what was my issue with this off the top of my head. I may need to redownload and try again, because I know I had an issue, reflashed and it fixed that issue, but then a new issue popped up, reflashed, fixed that issue, but then a new issue popped up. I know one of my issues was apps not downloading from the market. Can't recall what the other 2 issues were.
I want to get some great battery life. I'd at least like to get 10-12 hours of moderate to heavy usage if possible. I guess I can try CM7 again, I just have my worries about it. Not sure why, I know there are guides on what fixes need to be install and all that. But for some reason it scares me, lol.
Thinking I might just go back to kinged kingdom and try some of the new kernels. I got pretty good battery life with it, and it is fast.
